Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model;

[0014] Figure 2 This is a structural schematic diagram from another perspective of the present invention;

[0015] Figure 3 yes Figure 1 Enlarged view of point A in the middle. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] See Figure 1 , Figure 2 This embodiment is a tensile sensor durability testing device for rapid cyclic testing. Figure 1 The middle frame 1 is horizontally set on the frame 2. The right side of the frame 1 is the stretching module 3, which is preferably a servo electric cylinder. The left side of the frame 1 is the rotating module 4, which is preferably a stepper motor 41. The output end of the stepper motor 41 transmits the rotational power to the rotating shaft 43 through the meshing of two gears 42.

[0018] Figure 1 The middle frame 1 is equipped with a test fixture 5. The left end of the rotating shaft 43 is hinged to the right end of the rotating rod 51. The right end of the rotating rod 51 is connected to the thrust bearing 52 at the tension end of the product under test 01. Figure 3 In the middle, the main body of the product under test 01 is connected to the right end of the tension rod 53. In this way, when the rotating module 4 is started, the rotating rod 51 rotates accordingly. Due to the presence of the thrust bearing 52, the tension rod 53 does not rotate with the rotating rod 51.

[0019] Figure 1 The right end of the tension rod 53 is connected to the main body of the product under test 01; the left end of the tension rod 53 is detachably hinged to the slide block 6. Figure 2The middle slide block 6 is slidably mounted on the frame 1 via the slide rail 61. The cooperation between the slide block 6 and the slide rail 61 can further limit the transmission of the rotational force of the rotating rod 51 to the tension rod 53. A fixing block 62 is provided extending outward from the right end of the slide block 6. The displacement sensor 7 is fixed inside the frame 1. The detection end of the displacement sensor 7 is connected to the fixing block 62. This addition of the displacement sensor 7 allows for the detection of the actual tension displacement and comparison with the servo cylinder data, avoiding mismatch between the actual data and the servo cylinder data that could lead to incorrect test data.

[0020] Figure 1 In the middle, the right end of the tension rod 53 is connected to the pressure sensor 8 by a hinged and detachable manner. The pressure sensor 8 is connected to the tension shaft of the servo electric cylinder 3 through a floating joint 9. The pressure sensor 8 adopts the sensor with the public number CN118641073B.

[0021] When testing the product under test is required, the product under test is installed between the tension rod 53 and the rotation rod 51. The rotation of the detection end of the product under test is achieved by the movement of the stepper motor 41, and the tension of the detection end of the product under test is achieved by the movement of the servo electric cylinder. In this way, the product under test can be rotated and stretched during the testing process.

[0022] During the stretching process, gear 42 will inevitably be subjected to the pulling force of servo electric cylinder 3. By setting a thrust bearing between gear 42 and frame 1, the situation where gear 42 cannot rotate due to the pulling force is avoided.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
